SPECIFICATION forming part of Letters Patent No. 717,480, dated December 30, 1902i v Application filed March 2l, 1902. Serial No. 99,317. (Nomodel.)

To all whom t may concern:

Be it known that I, ALFRED J. WHITE, a citi- Zen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented `a certain new and useful Improvement in Vulcanizers, of which the following is a specification. My invention has relation to improvements in vulcanizers for manufacturing rubber 1o goods, and has especial relation to the means whereby the parts'constituting the vulcanizer are locked together and unlocked. j

Heretofore the vulcanizers inuse for long articles are retained together by a large number of ordinary bolts, whose tightening and loosening involves time and labor to such a degree as to render the operation thereof exceedingly expensive.

The object of my invention is to provide zo means whereby'the parts constituting the vulcanizer may be rapidly, easily, and accurately clamped together and as easilyseparated when desired.

To attain the aforesaid objects, my invention consists inthepeculiar and novel construction, arrangement, and combination of parts hereinafter describedand then specifically pointed out inthe claims, reference being had to the accompanying drawings, form- 3o ing a part of this specification.

In the accompanying drawings, in which similar reference-numerals indicate like parts in the dierent figures, Figure lis a side elevation of my improved device; Figs. 2, 3, and

5 4c, details used in my improved device and which will bei described later; Fig., 5, a side view of the vulcanizer-body with the clamping devices removed; Fig. 6, a section at the line m of Fig. 5; Fig. 7, a section at the liney 4o of Fig. 5; Fig. 8, a section at the line e of Fig.

5o drag.

form a long rectangular box and in ordinary cases usually exceed fifteen feet in length, and they have on their` inner adjacent faces longitudinal indentations of the required shape to produce the article to be vulcanized. In the main body portions of both the cope 1 and the drag 2 are steam-chambers 3 and 4c. These steam-chambers 3 and 4 may be of any preferred or desired pattern, the one in the cope being shown as substantially a square chamber into which project integral bafiieplates 5, by which means the steam is deiiected from side to side in order to more evenly distributethe heat which is used in vulcanizing articles in the device. In the lower portion of the drag 2 the steam-chamber consists of longitudinal pipes separated by narrow septums, by which means the steam is compelled to traverse backward and forward the entire length of the device for the same reason as is explained in connection with the upper part 1. These steam-chambers both have induction and eduction pipes for the inlet and outlet of live steam.

Fastened on the upper face of the cope 1 are a plurality of plates 6, extending transversely across the top of the cope and provided at each corner with ears 7, perforated centrally. On both sides of the vulcanizer are pairs of studs 8, projecting from the body portion of the vulcanizer and each inclosed by a friction ring or sleeve 9. These sleeves are placed in pairs directly above one another, and the number of pairs used on each vulcanizer is determined by the quality of work to be performed by the device, as well as the length of the vulcanizer. At each end of the vulcanizer, on both sides, are projecting lugs 10, integral with their respective parts. Extending between the ears 7 and revolubly journaled therein are shafts 11. Mounted and slidable lengthwise on the shafts 11 are rocking arms 12. The rocking arms 12 at each end of the vulcanizer extend vertically above the shaft 11, and at each end, extending between each pair, areshort links 13, united in the center by a pin, fromwhich extends vertically a hook 14. "The ro'cking arms l2, intermediate of the end arms, have no vertical portion extending above the shaft 11, but simply depend therefrom. The lower ends of the arms 12 are slotted and are aranother.

ranged to inclose a longitudinal horizontal shaft 15. This shaft 15 is designed when the rocking arms 12 are substantially vertical to lie along the sides of the vulcanizer substantially parallel and central with. the joint between the cope and the drag. This shaft 15 is splined and screw-threaded throughoutits entire length. Mounted on this shaft 15 are clamps 16, held from rotating on said shaft by means of the spline and held in place longitudinally between clampingnuts 17, by which their longitudinal position is determined. The outer faces of these clamps are substantially flat, excepting a boss 18 on each, placed thereon for strength. On the inside face of these clamps (see Fig. 2) is an open` ing having flaring sides. The diameter of this opening is such that it will inclose the outer peripherics of the sleeves 9 on the studs 8, and as the clamps are moved in one direction they will engage the studs S, and consequently cause the halves of the vulcanizer to more closely approach and press against one This shaft 15 when the rocking arms 12 are vertical will pass between the lugs 10 on the ends of the vulcanizer, and in order to cause the clamps 16 to engage the sleeves 9 on the studs S a nut 19 is placed on the shaft 15 outside of the lugs 10. As before stated, the lower ends of the rocking arms 12 are slotted and inclose the shaft 15, and the positions of the rocking arms 12 are located by adjusting the nuts 20, meshing on the threads of the shafts 15.

The operation of the vulcanizer is as follows: Green material, such as unvulcanized rubber, is placed in the mold portions of the drag, and the cope 1 is placed in position on top of the drag and the rocking arms then placed in a vertical position, by which movement the clamps swing closely up against the sides of the vulcanizer, but not in engagement with the sleeves 9. The nut 19 is then revolved,drawing the shaft 15 and the clamps 1,6 to the right in Fig. 1, causing each clamp to engage with the flaring sides of its interior, opening the sleeves 9, and if for any reason one clamp does not perform its peculiar function accurately at this time its position may be adjusted by means of the adjusting-nuts 17, so that each clamp will bear evenly and firmly on the sleeves 9. The description which has been heretofore given has been more with a reference to the mechanism on one side of the vulcanizer; but as both sides are identical the pressure will be uniform over the entire device. Steam is then turned into both steam-chambers for a desired and predetermined length of time to elect the necessary vulcanization of the green products in the molds. When this has been accomplished, the steam is shutoff and the tightening-nuts 19 released, allowing the clamps to free themselves from engagement with the sleeves 9. The hooks of a crane are then inserted in the hooks Maand power being applied to the crane the cope is lifted free from engagement with the drag. In effecting this last 'operation attention is directed to Fig. 9, wherein it is seen that the raising of the hook 14 breaks the joint between the links 13, thereby drawing inwardly the upper ends of the rocking arms 12 on their pivots, the shafts 11 swinging outwardly the clamps 16 from contact with the sleeves 9 on the drag 2.

It will be noticed in Fig. 9 that the tightening-nut 19 is omitted from the shaft 15 at the left of the device to more clearly show the shaft and position of the lugs 10.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
